Answer: 1-Propene has
eight sigma bonds and
one pi bond.
Explanation: The lewis structure of 1-Propene is shown below. All sigma bonds are highlighted by
blue color and the pi bond is highlighted by
red color.
Carbon having four unpaired electrons in its excited state can form four covalent (sigma bonds) bonds. In given structure the orbitals containing unpaired electron in sp³ hybridized C undergo head to head overlap with three hydrogen atoms having single unpaired electron and orbital of other sp² hybridized carbon in same fashion. So, four sigma bonds are formed by sp³ hybridized carbon atom.
The doubly bonded carbon atoms also form sigma bond but two unpaired electrons of these two carbons undergo the formation of pi bond. This pi bond forms when the orbitals overlap along the plane perpendicular to the existing sigma bond resulting in the formation of single pi bond.
Answer:
this data is both accurate and precise
That would be the crust (outer layer), mantle (semi-molten inner layer) and finally the core (the solid iron core of our planet). hope i helped :)
